Abstract
The invention provides a special-shaped steel pipe which is of an integral structure. The cross section of the special-shaped steel pipe is P-shaped, the shape similar to a P is formed by outwards and vertically extending and flanging one side of a hollow rectangular pipe as a main body, the special-shaped steel pipe is formed at one step through rolling or punching, and a seal of the rectangular pipe is a high-welding seal. The P-shaped pipe is formed by outwards and vertically extending and flanging one side of the rectangular pipe, and the special-shaped steel pipe serves as a section to be widely applied to various parts higher in requirements on sealability and matching gap. Especially, when the special-shaped steel pipe of the structure is adopted in the process of manufacturing an automobile door frame, welding process can be reduced, materials can be saved, and production cost can be lowered; manufacturability is guaranteed, and production efficiency and product quality are improved.
Description
Technical field
The present invention relates to section bar field, relate in particular to a kind of P type high strength opposite sex steel pipe.
Background technique
Existing section bar mostly is rectangular tube, and when use, flange processing need to be carried out in some place, and its basic skills is on the rectangular steel pipe of standard, to weld an angle steel or alloyed steel lath.Utilize the method in the time that section bar is processed: need to consume a large amount of welding rods, postwelding need be polished with emery wheel butt welded seam, wastes time and energy, and efficiency is low, and cost is high, manufacturability is poor simultaneously, affects quality of product.
Summary of the invention
The technological deficiency that while processing for overcoming existing rectangular tube flange, manufacturing efficiency is low, manufacturability is poor, the present invention proposes a kind of P type high strength opposite sex steel pipe.
For this reason, technological scheme of the present invention is: a kind of different in nature steel pipe, is characterized in that: this opposite sex steel pipe is monolithic construction, and its cross section is P shape; One side of the rectangular tube that described P shape is is hollow by main body is a vertical approximate P word shape that extends flange formation outwards.
Improve and be for the one of technique scheme: be simplification of flowsheet, reduce costs, described different in nature steel pipe is one-time formed by steel plate roll-in or punching press; For improving processing quality, the sealing part of described rectangular tube adopts welding manner sealing.
Beneficial effect:
The present invention, by by rectangular tube on one side outwards the vertical flange that extends form P shape pipe, be widely used in as section bar the component that various sealings, matching gap are had relatively high expectations.Especially in automobile door frame manufacture process, adopt this structure opposite sex steel pipe, can reduce welding procedure, save material, reduce production costs; Make manufacturability be guaranteed, improve production efficiency and product quality simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing section bar;
Fig. 2 is structural representation of the present invention.
Number in the figure is: 1, rectangular tube; 2, angle steel; 3, welding position.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, be the structure of existing section bar, be welded as a whole and form at 3 places, welding position by rectangular tube 1, angle steel 2.
As shown in Figure 2, a kind of different in nature steel pipe, this opposite sex steel pipe is monolithic construction, its cross section is P shape, one side of the rectangular tube 1 that described P shape is is hollow by main body outwards vertically extends 10 ㎝, then the part of stretching out is carried out to flange processing, forms an approximate P word shape.
For reducing technological process, reduce production costs, described different in nature steel pipe main body is one-time formed by roll-in (also can adopt punching press); For improving welding quality, the sealing part (being welding position 3) of described main body rectangular tube adopts the method solder up of contact welding.
The present invention, by by rectangular tube on one side outwards the vertical flange that extends form P shape pipe, be widely used in as section bar the component that various sealings, matching gap are had relatively high expectations.Especially in automobile door frame manufacture process, adopt this structure opposite sex steel pipe, can reduce welding procedure, save material, reduce production costs; Make manufacturability be guaranteed, improve production efficiency and product quality, is convenient to promote the use of simultaneously.
Claims (2)
1. a different in nature steel pipe, is characterized in that: this opposite sex steel pipe is monolithic construction, and its cross section is P shape; One side of the rectangular tube that described P shape is is hollow by main body is a vertical approximate P word shape that extends flange formation outwards.
2. the different in nature steel pipe of one according to claim 1, is characterized in that: described different in nature steel pipe is one-time formed by roll-in or punching press; The sealing part of described rectangular tube adopts welding manner sealing.
